SIREN TOY WITH SPARII PRODUCING DEVICE Filed June 18, 1932 anventorPatented Feb. 28, 1933 PATENT OFFICE CARL ARNOLD, OF'NURMBERG, GERMANYSIREN TOY WITH SPARK PRODUCING DEVICE Application filed June 18, 1982,Serial No. 617,964, and in. Germany February 24, 1.982.

This invention relates to a toy with siren and spark producing deviceactuated by a rack drlving mechanlsm.

Siren toys for this purpose are already known which are operated byplacing in the mouth and blowing air therein. These measures forproducing soundswere not perfect from a hygienic point of-view. Thespark beams could not be produced in conjunction with the siren sound.These objections are overcome by the toy hereinafter described.

An embodiment of the invention is illustrated by way of example in theaccompanying drawing in which 2- Figure 1 shows the toy in sideelevation partly in section.

Figure 2 shows the siren in top plan view, one half with the top plateremoved, and, in section in the other half.

Figure 3 is a top plan view of the emery wheel fixing device.

Above a known rack driving mechanism a or the like, provided withreturning spring,

' a casing, cap 0 or the like, is arranged,-whic has air-holes b, and ispartly closed by a cover likewise having an air-hole d. In the interiorof this casing a a second casing 'ihaving air-holes h is mounted on thedriving mechanism shaft b. Any desired number of fan blades k of anysuitable shape are fixed on the interior of the casing i. The blades iscause rotation .of the casing Flaps Z are likewise fixed on the drivingmechanism shaft 9 and carry oscillatably mounted cerium stone levers mwhich are gyrated by the shaft g. The cerium stones carried by thelevers m bear against an emery wheel a loosely mounted on the shaft 9.The emery wheel it must be loosely mounted in order not to impair therapid movement of the cerium stone levers and of the blades of thesiren, which is necessary for producing the sparks and the sounds. Inorder, during the gyrating movement of the oscillating levers, not toimpart a too rapid rotary movement to the loosely mounted emery wheelowing to the friction produced between the wheel and the rotating shaft,which movement would prevent the pr duction of the sparks, a flap o isprovided on the upper side of the siren and carries a strip of softmaterial such as rubber, cardboard or the like. This strip p bearsagainstthe emerydisc during the production of the sparks and only allowsthe wheel to rotate slowly. Intensive sparking is thus produced. Bridgesfixed on the siren carry a disc 4 shaped as a head or the like'andprovided with windows. The sparks produced pass through these windows orilluminate same in the event of coloured transparent panes being aflixedthereunder.

The toy operates in the following manner:

By exerting pressure on the rack of the driving mechanism the shaft 9 israpidly rotated together with the casing 71 fixed thereon. Owing to therotation air will be drawn through the cover hole at and propelled bythe blades is towards the holes h in the rotary casing z. The air flowsout from these holes through the holes I) of the stationary casing a. Asiren like noise is thus produced which can be made louder or feebler byvarying the pressure exerted on the rack. At the same time as the sirenis sounded, the spark producing device Z, m, a connected to the driving75 mechanism shaft is operated.

I claim 1. A siren comprising "in combination a rack driving mechanismhaving a returning spring, a stationary casing provided with soair-holes fixed on said mechanism, a cover on said casing, a drivingshaft in said mechanism, a rotary casing provided with airholes fixed onsaid shaft and surrounded by said stationary casing, and blades on theinterior of said. rotatable casing adapted to (lrawair into saidrotatable casing and to expel same through the holes in said stationarycasing to produce a siren like noise.

2. A siren toy as specified in claim 1, comprising in combination withthe stationary siren casing and the shaft, oscillatable levers carryingcerium stones fixed on said shaft above said casing, an emery wheelloosely mounted on said shaft adapted to co-act with 95 said ceriumstones to produce sparks during the rotation of said shaft and theproduction of the siren like noise.

3. A siren toy as specified in claim 1, comprising incombination withthe stationary siren casing and the shaft oscillatable levers carryincerium stones fixed on said shaft above sai casing, an emery' wheelloosely mounted on said shaft adapted to oo-act with said cerium stonesto produce sparks during the rotation of said shaft and the productionof the siren like noise, a flap on the upper side of said casing, and astrip of soft material carried by said flap adapted to bear against saidemery wheel to brake said wheel and to ensure relative movement betweensaid cerium stones and said wheel.

In testimony whereof I aflix my signature.

CARL ARNOLD.
